UNITED STATES PATENT QFFIQE DANIEL E. EATON, OF BOSTON, MASSACHUSETTS,ASSIGNOB TO HIMSELF AND P. O

EATON.

BURGLAR-ALARM.

Specification of Letters Patent No. 13,738, dated October 30, 18 55.

To all whom it may concern:

Be it known that I, DANIEL E. EATON, of Boston, in the county of Suffolkand State of hI-assachusetts, have invented an Improved BurglarAnnunciator or Alarm Apparatus; and I do hereby declare that the same isfully described and represented in. the following specification and theaccompanying drawings, letters, figures, and references thereof.

In such drawings, Figure 1, denotes a side elevation; Fig. 2, a topview, and Fig. 3 an end elevation, of my said improved alarm apparatuswhich when in use is to be fastened to the side of a door frame, andnear to the top or upper part of the door thereof, the working parts ofit to be hereinafter described. being fixed to a metallic frame orbracket, A, provided with two shelves, 0, being the lower and b theupper as seen in Figs. 1, and 2. Upon the lower of these shelves thereis arranged a lamp, B, upon which and near to its wick tube, 0, is fixeda match holder, C, composed of a thumb spring, (Z, and a stationaryprojection or post, 0, (arranged as seen in Figs. 1, and 2,) the springpressing toward the post so as to support a match when it is placedbetween them.

Above the upper shelf, Z), there is a horizontal shaft D, which issupported by a bracket f, and a post E, extended upward from the shafta, such shaft being connected to the inner end of a coiled spring F,whose outer end is attached to the bracket or stud f, projectingtherefrom.

Between the wick tube, 0, and the match holder C, and fixed to one endof the shaft D, is an igniting sector, G, whose inner surface or thatnext to the match holder is made rough in any proper manner, so thatwhen the sector is moved against the explosive composition of thefriction match sustained by the match holder it will fire or explode thesame. The shaft, D, has also affixed to it an escapement hammer .or cookH, which is simply an arm of metal arranged close against the outer sideof the post, E, and directly over an escapement rod, I, supported on orby a spring, 9, affixed to the shelf, a. Under the shelf, a, there isarranged any alarm apparatus, X, such as is in common use in alarmclocks,

the striking hammer of said apparatus be ing seen at K. It is made toact upon its bell, L, arranged as seen in Fig. 1.

By the pressure of the spring, F, the arm or hammer is borne down uponthe top of the escapement rod, I, so as to depress the said rod and thespring upon which it rests, the said rod being made to extend downwardand hook under a bent arm, h, extending from the rocker shaft of thepallet, i, of the escapement wheel K, of the alarm apparatus. hen therod I, is relieved from the pressure of the hammer, the spring, 9, willlift the rod, so as to cause it to move the pallet, 1', up to the wheel,70, in such manner as to prevent the escapement wheel from vibrating thesaid pallet, so as to cause the hammer K, to strike upon the bell.

Underneath the shaft D, and turning horizontally upon the shaft, 6, is atrigger or lever M, which has a bolt N jointed to it and made to extendand slide through a post E, and also to enter a hole, Z, made throughthe hammer H, when said hammer is turned down into a vertical position.The said bolt should be so applied to its trigger lever in such mannerthat when the latter is moved in one direction it shall move the boltfor ward, and when moved in the opposite direction it shall retract thesaid bolt.

The annunciator or apparatus herein above described is not only intendedto sound an alarm, but also to inflame a lamp, and when it is used onearm of the trigger should project by the door in such manner that whilethe door is being opened, it may move said trigger far enough to producea complete withdrawal of the bolt from the arm or hammer H, in orderthat said arm when. thus relieved from retention in a vertical positionby the bolt may be thrown by the spring, F, smartly over and upon thetop of the rod, I. In my said apparatus, the match holder is stationarywhile the igniting surface or sector G is movable or is made to moveagainst the match when sustained by the said holder, the said sectoroperating to throw the extinguisher, 0, off the wick at the same time itignites the match. The trigger lever may be connected with the wire of abell pull of a street door of the house in which the annunciator may be,the connection being such, that when said bell pull is drawn outward, itmay cause such a movement of the trigger as will put the annunciator inoperation. In this Way my alarm apparatus may be made especially usefulto a physician or apothecary or any person whose avocation may cause himto be occasionally awakened during the night time, the apparatus notonly sounding an alarm but at the same time striking a light.

My invention or improvement rests in the peculiar arrangement of theoperative parts, situated above the shelf, a, such causing them tooperate with great efficiency and with little liability of derangement.

I do not claim the combination of a lamp and an alarm apparatus, a matchholder and an igniting surface; nor employing therewith a contrivancefor casting the extinguisher off the lamp, but

What I do claim is,

Arranging both the igniting sector G, and escapement hammer, H, on onerotary shaft (controlled by a spring as above set forth), in combinationwith so arranging the wick tube, 0, the match holder C, and the escapement rod, I, that immediately after the trigger bolt N, has beenwithdrawn from the escapement hammer, not only shall such hammer bethrown over upon the top of the escapement rod, but the igniting sectorbe caused to discharge the extinguisher off the wick tube as described.

In testimony whereof, I have hereunto set my signature this eleventh dayof September A. D. 1855.
